How to gain easy adoption in market? | I will not promote

We are building an evaluation tool and have an MVP, but the problem right now is that nothing is integrated or in structure, and we can't directly provide the tool to evaluate rather we need data from clients to run the tool and evaluate on our end. So we thought of making a pip library or MCP. But we really dont have any use of MCP right now so we are going with pip library, but the thing is if we make it into a library then won't it become open source rather than proprietary software? And since it's only two people right now and we are in really early stage we dont want to waste time on making a full blown application, so how can we go about it?
Any suggestions on removing friction for early adoption or navigating this would be much appreciated.
